i To all wtm t may concern:

Be it known that I, PETER B. CRANE,

`citizen of the` United States, resident of yLong Lake, Hennepin county, Minnesota,

being arranged so that those of one group` will travel in the furrow pleviouslyvcut by the other group.

A further object is to provide ay plow which cany be easily operated` andr is thoroughly efficient for the purpose designed. y

The invention consists generallyin vari- "ous constructions and combinations, all. as hereinafter' described and particularly pointed out in the claims. c f

In the accompanying drawings forming part of this speciiication, Figure 1 is a plan view of agang plow embodying my invention, Fig. 2 is a side elevation, partially ,in section, of the same, Fig. 3 is a detail sectional view of a beam of one of the groups of beams, Fig. 4 is a similar sectional view, showing the other type of` beam, Fig. 5 is a detail sectional view, showing the preferred manner `of mounting the plow disk on the beam. y

In the drawing, 2, 3 andB represent the side and middle rails of the frame, and 4 and 5 the end rails thereof. At the forward end of the frame isa carryingk wheel 6,

mounted` on `an arm 7 that is vertically adjustable in albearing 8 on said frame Aand operated by means of a link 9 Iand a `lever 10,'this `being ordinary construction in machines of this type. A side carrying wheel, corresponding to the one shown in front, 1s also provided and mounted` in a similar manner, and which Iy will indicate by the same reference numerals. The lrear end of the machine has a carrying wheel 11` supported on an armf12 that is vertically slidable in the frame of the machine and 1s operated by means `of a lever 13 having a link 14 connecting said lever withy a sleeve 15 between two collars 16 on said arm. A fork device 17 is mounted on said frame and normally prevents the arm from turning in its bearing. The arm 12 is free to rotate in its bearing, as well as having a sliding movement therein, while the arms 7 fitting within rectangular sockets are held against rotary movement. Agroup of disks 20 are provided for maklng the initial cut or furrow in the soil. These disks are arranged one in advance of the other and odset to make a corresponding number of furrows. Each of these disks is provided with a hub 21 in its convex face, provided at one end with an annular flange 22 that is held against the beam 23 of the disk by means of flanged plates 24. A stud 25 is mounted in the beam and has a bearing for the hub 21. The forward end of the beam is pivotally connected with the rail 3 of the frame, said rail being diagonally arranged at an angle to the direction of movement of the machine, and provided for the proper oset of the plows with respect to one another. The beams are free to oscillate vertically on their pivotal connections with the frame and each beam has a flexible connection, such as a chain 26, connecting it with an operating lever 27 mounted on the machine frame. By means of this lever each disk can be raised or lowered, independently of all the other disks. y

Each beam 23 is provided with a socket 28 in which the horizontal arm of a bracket 29 is slidable. This bracket has an upright arm upon which a series of weights 30 are placed, one above another. A set screw 31 is mounted in the beam 23 in position to engage the `bracket29 and lock it on the beam. When this set screw is loosened, the bracket may be y moved toward or from the pivot of the disk 'backward oscillation of said beams but allowing them to swing upwardly and forwardly to raise the disks out of the ground and pass over any obstruction therein without interfering with the movement of the other disks. The plate 37 has a concave under surface which bears on the hub 35 so that the load on the disk is transmitted through its supporting beam without any tendency to shear the pivot pin 34. The pivots of the beams 34 are, as shown, in the rear of the pivots of the disks thereon, and the shoulders 36 engaging the plate 37 will limit the backward oscillation of said beams, while the forward movement of the machine will tend to push the disks 23 into the soil and complete the depth of cut of the-furrow. The hub 35 has a long bearing on the pin 34 and with the concave face of the plate 37 will form a substantial, durable bearing for the disk supporting beam on the frame of the machine. This I have found a simple and economical method of mounting the push beams on the frame, as the parts are few in number and easily accessible for substitution or repairs.

Flexible means, such as the chains 38, are attached to the lower ends of the beams 33 and to operating levers 39 mounted on the frame of the machine. These push beams 33 may be lifted by the operation of the levers 39 to regulate the depth of cut of the disks carried thereby and, if desired, the machine may be weighted to force these disks a greater depth into the soil. I do not, however, depend upon weights fordepressing the disks 32, as the forward draft of the machine will have a tendency to make these disks dig into the soil without the aid of weights, usually required where the pivot of the beam is in advance of the disk.

In the operation of the machine, the disks 20 are set to cut a series of shallow furrows and the disks 32 following after the disk,20 and in slightly staggered relation with respect thereto will deepen the cut of the furrows, the depth being regulated by the levers controlling the adjustment of the beams 33. The forward disk 32 may be set to cut a deep or shallow furrow, as desired, on the first time around the field, and on the second time around may travel in the furrow previously cut by the rear disk 20.

In various ways the details of construction herein shown and described may be modified and still be within the scope of my invention. I

I claim as my invention:

l. Adeep soil gang tilling machine comprising a frame having carrying wheels, a series of beams pivotally connected to said frame, .a series of disks mounted on said beams, the pivots of said beams on said frame being in the rear of the centers of said disks, whereby upon the forward movement of said frame said beams will voperate to push said disks into the soil, said disks being free to rise and fall in the soil during the operation of the machine, and means for regulating lthe depth of cut of said disks.

2. A gang tilling machine comprising a frame having carrying wheels, beams pivotally connected with said frame, a series of disks mounted on said beams, the pivots of said beams on said frame being in the rear of the centers of said disk, whereby said beams will operate to push said disk into the soil during the forward movement of the machine, operating levers, and flexible means connecting s aid beams with said levers for regulating the depth of the cut of said disks, said flexible means allowing said disks to rise and fall inthe soil during the operation of the machine.
